Abstract
In this paper, the time synchronization algorithm for orthogonal frequency division multiplexing (OFDM) system is analyzed. Based on the algorithm using PN sequence, different methods of setting adaptive detection threshold have been proposed before. We analyze the performance of the methods theoretically, and propose a method which is suitable for large dynamic range of SNR. The simulation indicates the method can satisfy the demand of OFDM system in multi-path fading channel.
